How UK income tax works
Income tax is banded: you only pay each rate on the portion of income that falls within that band. Everyone gets a tax-free personal allowance of £12,570. Income above that is taxed at 20% up to £50,270, then 40% up to £125,140, then 45% beyond. National Insurance is separate and adds to the total — the self-employed pay Class 4, employees pay Class 1.
A quirk catches higher earners: once you pass £100,000, your personal allowance is withdrawn at £1 for every £2 over the limit, vanishing at £125,140. That creates an effective 60% rate on that slice of income — which is why pension contributions are popular around that level.
